MODAL SPLIT INDICATORS METHODOLOGY FOR TERRITORIALISATION OF AIR TRANSPORT APRIL 2020 MODAL SPLIT INDICATORS METHODOLOGY FOR TERRITORIALISATION OF AIR TRANSPORT SUMMARY The methodology for ‘territorialisation’ of air transport data in the European Union, presented below, has been developed by Eurostat. ‘Territorialisation principle’ means that only freight and passenger transport performed within the territory of a country is considered. In terms of air transport, 'territorialisation' means that the transport performed in the air space is allocated to the countries overflown on each air transport route. The aim of territorialisation is to compare shares of each transport mode into the total transport performance in the European Union and also at national level. This is called the ‘modal split’ between the different transport modes. ‘Territorialisation’ is straight-forward for transport by road, railway and inland waterways, as it takes place on the territory of a country. The calculation is more complex for maritime and air transport, which only uses airport or port infrastructure in the country where the transport starts (origin) and where it ends (destination), and merely passes through the national waters or airspace of other countries on the route. ‘Transport performance’ is measured in tonnes-kilometres (tkm) for freight and passenger-kilometres for passengers (pkm). A tonne-kilometre is defined as one tonne of freight flying for one kilometre; a passenger-kilometre is defined as one passenger flying for one kilometre. The total tkm or pkm on an air route are, first, calculated based on passengers/freight transported between pair of airports and a distance matrix; and, then, the calculated tkm/pkm are ‘territorialised’ by allocating them proportionally to the countries overflown, according to the distance flown over each country. Eurostat maintains a database of distances (distance matrix) between EU airports, and between EU airports and World-wide airports. The distances are based on the ‘greater-circle’ distance, which is the shortest distance between two points on the surface of a sphere (i.e. the shortest possible flight path between the airport of origin and the airport of destination). This shortest distance is then split into distance legs for each country overflown during the flight in order to 'territorialise' the transport performance. The distance for each country is based on its national airspace, which includes territorial waters of 12 nautical miles off its coast. It must be highlighted that the ‘territorialised’ air transport performance is a concept used only for comparing the transport modes' activity at countries' level. The resulting statistics are not comparable with statistics on energy consumption in transport or with GHG emissions as these are based on different methodologies. A number of concrete examples of application of the methodology for different flight routes are given towards the end of this document. These examples include national flight routes (including routes passing over another country, flight routes to overseas territories, ‘intra-EU’ flight routes between two Member States (including routes passing over other countries) and international ‘extra-EU’ routes between a Member State and a country outside the EU.

The White Paper lists ten goals for a competitive and resource efficient transport system in Europe. In order to monitor progress towards certain of these goals, comprehensive and comparable data on passenger-km and tonne-km by distance travelled is needed for all modes of transport. The transport statistics data collection, in its significant part, is based on legislation applied by EU Member States, European Free Trade Association (EFTA) countries and certain candidate countries. Transport performance is measured in tonne-km (for freight transport) or in passenger-km (for passenger transport). However, the legislation for collecting data on the different transport modes varies to some extent, reflecting the peculiarities of the specific transport modes and to the data needs for each mode. 2 MODAL SPLIT INDICATORS: WHAT DATA ARE NEEDED FOR TRANSPORT MODES 2.1 MODAL SPLIT INDICATORS Modal split indicators (MSI) are defined as the share of each mode of transport in the total transport performance, measured in tonne-kilometres or passenger-kilometres. MSI measure the composition of transport performance, i.e. the importance of each mode of transport for the total freight or passenger transport, and the evolution over time in the share of each transport mode. 2.2 TERRITORIALITY PRINCIPLE Dependent on the transport mode in question, transport performance is reported by the countries according to the "territoriality principle" (rail and inland waterways) or is 'territorialised' by Eurostat from the detailed region-to-region data (road freight). In practice, only the transport performance that takes place on the territory of the country, performed by any operator (domestic or foreign) is taken into account by territorialised transport statistics. In the case of international transport, only the leg of the journey that takes place within the territory of the country is considered. Within the frame of transport statistics, according to the ‘territorialisation principle’, only freight and passenger transport performed within the territory of a country is considered. This also includes all parts of cross-border transport performed on the country’s territory, irrespective of whether the journey is only crossing the territory or whether its origin or destination lies within the country. 1 https://ec.europa.eu/transport/themes/strategies/2011_white_paper_en Page 4 of 26 MODAL SPLIT INDICATORS METHODOLOGY FOR TERRITORIALISATION OF AIR TRANSPORT Rail and inland waterways statistics, as they are reported by the countries to Eurostat according to the legal acts on statistics in force2, are already reported following the ‘territoriality principle’3 and data refer only to transport performance that has taken place on the territory of the countries. In contrast, road freight transport is currently collected4 on all movements of vehicles registered in the reporting country (i.e. the 'nationality principle'), whether these are carried out within the territory of the country or abroad. Road freight transport data, particularly for international transport, need to be recalculated according to the "territoriality principle". This is done by Eurostat on the basis of journey- related data, with the help of a distance matrix that models the most likely route taken (the fastest route). This allows cross-border transport journeys to be ‘cut’ into national legs for each country of the route5. Furthermore, the data collections6 on air and maritime transport cover passengers and freight transported between a pair of airports or ports, without having data reported in tonne-km or passenger-km. Consequently, the main challenge in calculating modal split is being able to use coherent data series across the different transport modes, based on methodologies that are as comparable as possible. 3 AIR TRANSPORT STATISTICS 3.1 AIR TRANSPORT DATA COLLECTION Eurostat collects air transport data expressed in tonnes and in number of passengers carried between pairs of airports according to Regulation (EC) No 437/2003 of the European Parliament and of the Council of 27 February 2003 on statistical returns in respect of the carriage of passengers, freight and mail by air. According to this legal act, data are reported for commercial air services. This means that military flights, flight activities relating to aerial work, hospital flights and any other non-commercial flights are excluded. The legal act specifically states that detailed reporting (on transported passengers/cargo between pairs of airports) should be done by airports with traffic in excess of 150 000 passenger units annually. For the smaller airports, aggregated reporting is sufficient. 3.2 DISTANCE OVERFLOWN AND CALCULATION OF TONNE-KM AND PASSENGER-KM In addition to these data on volumes of freight and passengers transported, the distance
